ROTARY VALVE;

APPLICATION HhED IAN-12. 1915.

za'zzzu 42 d22 Specification of Letters Patent:

ideas.

Anplication filed January 12', 1915.

To all whom it may concern:

Be it known that l, WILBUR Sonur'ru, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of lllinois, have invented certain new and useful Improvements in Rotary Valves,

of which the following is a specification.

lily invention relates to lmprovements lIl rotary valves for internal combustion engines, the present application being in-part a division of my pending application, Serial No. 827,069, filed March 25th, 1914, for rotary valves for internal combustion engines.

The object of this invention is the pro duction of a rotary valve mechanism in which the valve proper will be so connected with the driving means cooperating there- 'with as to permit of read y and easy disconnection of the valve from said driving mechanism, and replacement thereof without disturbing the timing of the valve relative to the reciprocations ofthe pistons of the engine.

A further object is the production of valve mechanism as mentioned which will be of simple construction and efficient in operation.

Other objects will appear hereinafter.

lVith these objects in view, the invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference toi the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a top plan view of a valve mechanism embodying my invention the same being shown applied to an internal combustion engine, Figs. 2- and 3 are elevations of the opposite ends of the construction shown in Fig. 1, Fig. l. is a central vertical section of the construction shown in Fig. l, and Fig. 5 is an end elevation of the rotary valve detached.

The preferred form of construction as illustrated in the drawings is applied to an internal combustion engine consisting of cylinders 1, the upper ends of which are closed by a plate 2. Said plate is formed with inlet and exhaust ports which are-controlled by the valve mechanism in the manner clearly set forth in my parent application, above referred to. This valve mechanism comprises a cylindrical housing 3 which is housing by bolts 7 BPatentet Nov. is, 1915i Serial No. 1,805.

secured by bolts 4.- to the upper ends of inders 1. One end of said housing by a head consisting of two sections which are secured together the opposite end of said housing being closed by a head 6. The heads 5-5 and 6 are secured to the respective ends said and 8 respectively. The

0377; 1S closed 5 and 5 y screws .1

heads 55 outwardly projecting flanges 9 and 10 respectively, which are provided at the upper ends of cylinders 1, being fastened to said flanges by means of bolts 11 and 12 respectively.

l'lotatably mounted within the housing 3 is a" valve 13 of substantially cylindrical form and adapted, in operation, to control the inlet and exhaust ports communicating with the upper ends of the cylinders 1. construction and operation of the valve 13 so far as the same controls the inlet and exhaust of cylinders 1 forms no part of this invention, this construction being the subject matter of my parent application, above referred to. Hence, the detail construction of said valve, or its operation, will not be gone into in this case. It is desired to point out, however, that the axial passage 1%. formed through'the valve 13 and which constitutes the exhaust manifold of the valve connnunicates at one end with a passage 15 formed in the head 6 and which in turn conimunicates with an exhaust pipe 16 secured to and extending from the flange l0.

Rotation of the valve 13 is effected by means of a bevel gear 17 which is rotatably mounted upon a supporting stud 18 formed upon the inner side of the member 5. Ball bearings 19 are interposed between the stud 1S and the hub of said gear to alleviate friction. Formed upon. and projecting outwardly from the adjacent end of valve 13 is a plurality of pins or studs 20 which releasably engage correspondingly positioned recesses 21 formed for the reception thereof in the adjacent'side of gear 17. lVith this arrangement, it will be seen that an operative connection between said valve and gear isestablishcd which permits of disengagement of said valve from said gear upon sliding of'said valve longitudinally from said gear. The gear 17 meshes with a pinion 22 shaft 23 which its lower end fixed to the upper end of a is operativelyconnected at and 6 are also supported on,

The

.lOO

with the crank shaft of the engine or other driving element for effecting rotation of the interfered valve body at a speed properly timed-with the reciprocations of the pistons of the cylinders.

With the construction set forth then, it will be seen that, if it is desired to remove the valve and its housing for repairing, cleaning or renewing said valve, it is only necessary to remove the bolts 4, 7 and 12; When this is done, the valve housing and head 6 will be disconnected from the engine so as to permit of longitudinal sliding of the parts from the head 5-5 so as to effect disengagement of the studs 20 of the valve from' the gear 17 \Vhen said parts are removed, the head 55' will constitute a housing or support for the gear 17 holding the same in fixed relation with the engine cylinders and therefore maintaining the proper timing of the valve so that upon remounting of the latter, the proper timing will be secured without any adjustment. This is, of course, of great advantage since without the independent supporting means for the valve driving gear, upon demounting of the valve, the timing thereof would be disturbed and with which would subsequently result in considerable loss of time in readjusting the valve to secure the proper timing thereof.

By connecting the exhaust pipe 16 with the flange 10, instead of directly with the head 6, the necessity of disconnecting the head 6 from said valve, as would be the case when demounting the valve, were the other construction used, is obviated.

. \Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. therefore do not wish to be limited to the precise'details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
